Car Lights Up But Engine Won’t Start

Introduction

If you turn the key in your ignition and the lights come on but the engine doesn’t start, it can be a frustrating and confusing experience. There are a number of possible causes for this problem, and it can be difficult to know where to start looking.

Causes of a Car That Lights Up But Won’t Start

There are a number of possible causes for a car that lights up but won’t start. Some of the most common causes include:

* **Dead battery:** If your battery is dead, it won’t be able to provide the power needed to start the engine.
* **Loose or corroded battery terminals:** If the battery terminals are loose or corroded, they won’t be able to make a good connection with the battery, which will prevent the engine from starting.
* **Bad starter:** The starter is responsible for turning the engine over. If the starter is bad, it won’t be able to engage the flywheel and start the engine.
* **Fuel problems:** If there is no fuel getting to the engine, it won’t be able to start. This could be due to a clogged fuel filter, a bad fuel pump, or a leak in the fuel line.
* **Ignition system problems:** The ignition system is responsible for creating the spark that ignites the fuel in the engine. If there is a problem with the ignition system, the engine won’t be able to start.
